University of Rochester biologist documents novel form of adaptation through natural selection in the journal 'Science' It has been a basic principle of evolution for more than a century that plants and animals can adapt genetically in ways that help them better survive and reproduce. Now, in a paper to be published in the journal Science, University of Rochester biologist John Jaenike and colleagues document a clear example of a new mechanism for evolution. In previous well documented cases...

Deworming lambs can be minimized with rotational grazing and checking the animals' eye color, according to an Agricultural Research Service (ARS) study. Animal scientist Joan Burke at the ARS Dale Bumpers Small Farms Research Center in Booneville, Ark., and colleagues made this finding as part of a continuing collaboration with scientists, veterinarians, and extension agents from the Southern Consortium for Small Ruminant Parasite Control. The consortium was formed in response to the threats...

Community-based lymphatic filariasis education in Orissa State, India, increased treatment compliance from around 50% to up to 90%, according to a study published June 29 in the open-access journal PLoS Neglected Tropical Diseases. In their study, researchers from the U.S. Centers for Disease Control and Prevention, in partnership with the Church's Auxiliary for Social Action, an India-based non-governmental organization, and IMA World Health, a US-based non-governmental organization,...

Nematodes vanquish western corn rootworm pest The larvae of Diabrotica virgifera virgifera beetles wreak havoc on maize. Feasting on the plants' roots, they are estimated to cause $1 billion of damage every year in the US. Ted Turlings from the University of Neuchâtel, Switzerland, explains that the pest, known as western corn rootworm, only arrived in Serbia in the 1990s, but since then it has marched through at least 11 European countries. 'Pesticides work to control the...

ALACHUA, Fla., May 24 /PRNewswire/ -- Pasteuria Bioscience (http://www.pasteuriabio.com) has completed its manufacturing scale up and is successfully producing Pasteuria spores commercially. Pasteuria spp., a natural microbe prevalent in soil, has long been recognized as a promising biological control agent for nematodes. Until now, no one had been able to grow Pasteuria outside of the body of a nematode. Pasteuria Bioscience developed a proprietary manufacturing method to grow and...

Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) at the University of Birmingham have discovered that a gene called DAF-16 is strongly involved in determining the rate of ageing and average lifespan of the laboratory worm Caenorhabditis elegans (C. elegans) and its close evolutionary cousins. DAF-16 is found in many other animals, including humans. It is possible that this knowledge could open up new avenues for altering ageing, immunity and resistance...

Researchers at the Energy Biosciences Institute (EBI) at the University of Illinois have discovered widespread occurrence of plant-parasitic nematodes in the first reported nematode survey of Miscanthus and switchgrass plants used for biofuels. Lead researcher Tesfamariam Mekete, a U of I post-doctoral research associate, said the team's first step was to identify potential pathogenic nematodes of these top two energy-yielding cellulosic-ethanol feedstock plants. "Nematodes are a part of our...

A new combination drug treatment for parasitic intestinal roundworms shows promise in a test on a common laboratory species. Several drugs currently in use or in development control parasitic worms in the same way. That concerns health workers In developing countries where reinfestations often require repeated treatments. If worms develop resistance to one drug, the other treatments would likely fail as well. Raffi Aroian's research group at the University of California, San Diego recently...

Biologists at UC San Diego have discovered that a protein from a soil bacterium used to kill insects naturally on organic crops is a highly effective treatment for intestinal parasitic roundworms. These parasites, which include hookworms and whipworms, infect about two billion people in underdeveloped tropical regions and are cumulatively one of the leading causes of debilitation worldwide. The scientists report in the March 2 issue of the open-access journal PLoS Neglected Tropical Diseases,...

A common pasture plant could help foraging ruminants ward off damaging gastrointestinal nematodes that can cause illness and death, Agricultural Research Service (ARS) scientists report. Animal scientist Joan Burke at the ARS Dale Bumpers Small Farms Research Center in Booneville, Ark., along with colleagues at several universities, has patented formulations of Sericea lespedeza, commonly referred to as Chinese bush clover. The plant was introduced in the United States in the 1930s to...

Nematology
2013-09-30 13:49:26

Nematology is the study of nematodes, also known as roundworms, which first began in the nineteenth century. Like many fields of study, nematology began with ancient recordings and descriptions lacked elements of modern science. The oldest record of a nematode occurs in the Pentateuch in the fourth book of Moses known as Numbers. The reference, although not plainly stating roundworms or nematodes, is thought to refer to Dracunculus medinensis, a species that is native to the area near the Red...

Trichuris suis
2014-01-12 00:00:00

Trichuris suis is a species of whipworm that is classified within the Nematoda phylum. It can be found in warm tropical regions throughout the world but is rare in arid regions. Males reach an average body length between 1.1 and 1.5 inches, while females reach an average length between 2.3 and 3.1 inches. This species, and other members of the Trichuris genus, was given its common name because of its whip like appearance. The original definitive hosts of this species are pigs, but it is able...

Phasmarhabditis hermaphrodita is a species of roundworm that is classified within the Nematoda phylum. This species is found in soils where slug species from the Limacidae, Arionidae, and Milacidae families are located, with one common host being Deroceras reticulatum. The worm can be located in soil by using real-time PCR testing methods, a test that also distinguishes it from its similar relative, Phasmarhabditis neopapillosa. The life cycle of Phasmarhabditis hermaphrodita begins in...

Onchocerca volvulus
2014-01-12 00:00:00

Onchocerca volvulus is a species of roundworm that is classified within the Nematoda phylum. This species causes the disease onchocerciasis, more commonly known as river blindness. The life cycle of this species is dependent upon an intermediate host, typically the black fly, and a definitive host, which is always a human. Its lifecycle begins when a black fly ingests microfilariae from a human host by consuming blood. The microfilariae that were present in the skin of the human host now...

Trichinella spiralis
2014-01-12 00:00:00

Trichinella spiralis, sometimes known as the pork worm, is a parasite within the Nematoda class. It can be found in pigs, rats, humans, and bears. This worm causes trichinosis in humans, most often from consuming undercooked pork. This species is the smallest within its class, reaching an average body length of .16 centimeters. Females are twice as large as males, displaying a sexual dimorphism. The reproductive organs of females are unique to the species in that the front end holds developed...
